Abstract: In this paper, we describes a novel periodical electromagnetic structure. This hybrid structure consists of an absorber layer and a frequency selective surface (FSS) layer, so-called AbFSS structure. These two layers share one dielectric substrate. The absorber layer works at K band and the FSS layer performs at X band. The unit of this structure is numerically studied. A design procedure is developed after this study. Then an AbFSS antenna radome is modelled and applied to a 2x2 microstrip patch array. The characteristics of the array with and without this novel radome are researched. The characteristics include antenna gain and monostatic RCS. The comparisons of these characteristics of the array with and without the radome demonstrate that this radome is transparent at X band and absorptive at K band. This AbFSS structure can be easily achieved in Engineering and be a good candidate for the antenna radome.

Abstract: With the development of computer technology, computer-aided translation software is widely applied to translation. It is able to improve translation efficiency and quality. Meanwhile, it is in accordance with the requirement of market-oriented translation workshop. The paper compares the strengths and weaknesses of the major computer-aided translation software, which provides the software consumers with practical suggestion. The design principle is also discussed in the paper to facilitate the design of satisfactory computer-aided translation software to the users.

Abstract: In sensor networks, a reasonable distribution of sensor nodes is an important role for the improvement of sensor ability, information collection ability and network survival. For multilayer mobile sensor network, a tree-based deployment optimization scheme was proposed and better sensor coverage could be achieved by topology adjustment utilizing mobility of sensor node. Sink nodes complete mobile positioning of S nodes based on rectangle division method and bounding box algorithm, and achieve the distribution optimization of S nodes by establishing extending-tree of Sink node as the center. Results show that the location error ratio reduces with the increase of Sink nodes. Compared with initial random deployment network, the network coverage ratio after optimal deployment significantly enhances, which effectively improve the coverage sensor range of overall network.

Abstract: For the mobile cellular networks (MCN), a new analytical model which is the PH-renewal process to model is developed in this paper as a cost-effective performance tool to investigate the performance of the MCN. To the best of our knowledge, we have not found to analyze the performance of the MCN by the pure PH-renewal models. We apply the matrix-analytic approach and the PH-renewal process to explore the performance measure of the drop and block probabilities in the MCN. The numerical results show that the proposed analytical approach is more efficient than others.

Abstract: Precision guided weapons played important roles in war. For disturbing the guidance of laser, thermal infrared and TV, the Interference camouflage smoke material covering the visible light, thermal infrared and millimeter wave band, was studied in this paper. Meanwhile, the effects of combustion’s multi-band interference camouflage were proved in the experiment. And based on the calculation model of TV guidance seeker range, the analysis of multiband smokescreen camouflage interference effect was provided.

Abstract: In the production of coal, once an mine accident happens, timely monitoring and management are need, in order to ensure communication and rescue work. Using remote video monitoring system, ground or central monitoring personnel can conduct current-time underground monitoring, and can find potential accidents before they occur; in addition, personnel can monitor and record intuitively the safety production in underground work site . This paper begins with an overview of the coal mining enterprise remote video monitoring requirements, discusses the overall design, modules formation and implementation of Internet-based remote video monitoring system of coal mining enterprises programs, and finally presents the development and application of Internet-based remote video monitoring system of coal mining enterprises.

Abstract: By analyzing the detection accuracy and the testing speed of the Local Binary Pattern. we propose an improved LBP algorithm and apply it in human detection. Through the signs of the comparisons among neighboring pixels, it will get the histogram of the detection window. Then we can encode the global contour by the distribution coefficient of the histogram. when the Linear classifier is used, we propose a fast computational method that does not need to explicitly generate feature vectors and not require feature vectors normalization. experiment shows that this method has higher efficiency and can’t reduce the accuracy, it achieves 19 fps speed and can be used in a real-time system.
